The operation performs a morphological thickening. Similarly to other region morphology operations, thickening is conducted using a shape called kernel (or structuring element). There are two kernels: hit kernel and miss kernel, which are passed as parameters to RegionHitAndMissTransform. This operation's result is then added to the input region giving the output region. The filter uses internally predefined kernels, which are dual to those from ThinRegion filter.

This filter is available on Advanced Complexity Level.

• ThinRegion – Performs a morphological thinning on a region using predefined kernels.

• RegionHitAndMissTransform – Performs a hit-and-miss transformation on a region using arbitrary kernels.

• DilateRegion_AnyKernel – Performs a morphological dilation on a region using an arbitrary kernel.
